基于单片机的输液监控模拟系统

Design of Infusion Monitoring System Based on Single Chip Microcomputer

为解决传统人工监控输液中存在的滴液过快过慢及滴液结束后无提醒的弊端,设计了一种基于STC89C52单片机的输液监控系统,可以通过液晶显示屏实时监控滴液速度,并根据药物需求设置液滴速度报警阈值,如果滴液速度超出阈值,那么单片机将驱动步进电机进行正反转加大或减小滴速且蜂鸣器报警。当检测到药水瓶中没有药水时,蜂鸣器进行报警。

In order to solve the shortcomings of traditional manual monitoring transfusion,such as too fast and too slow dropping and no reminder after dropping,a transfusion monitoring system based on STC89C52 is designed,which can real-time monitor the speed of dropping through the liquid crystal display,the alarm threshold of droplet velocity is set according to the drug demand.If the droplet velocity exceeds the threshold value,the single chip computer will drive the step motor to increase or decrease the droplet velocity and the BUZZER will alarm.When it detects that there is no potion in the vial,the buzzer alarms.
